With a 2 min search I found a cyberpowerpc prebuilt for $700 that included a r7 5700 and rx 6700. And yes, you can absolutely get 60 fps at 1080p on some aaa titles; I don’t know where you get that idea you can’t, especially if you can tweak graphics settings (for the record, most pc gamers don’t even use ultra- high and medium presets are the most reasonable settings). I’m sure a title like Diablo 4 doesn’t require tuning at 1080p at all.
IMO the problem is not that you can’t block them but tooling. It is true that with the appropriate tools and work you can farm the data yourself and get everyone’s votes, but realistically most people aren’t going to go out of their way to do that. I see no reason why this would make lemmy better and instead just gives ammunition to bad actors. The poster above you is asking why we need to do more things to avoid bad actors as an effect of the change instead of avoiding that outcome. We know there will be bad actors, but we don’t need to make things easy for them. Maybe you were never gonna stop the guy willing to make an instance and look through all your votes, but you’d stop all the ones who wouldn’t be willing to put in the effort.
Problem with their logic is that, as stated in the article, goods such as preserved books are already used for recreation. Your idea that a catalogue of old media would prevent consumption of new media is provably false by example. People read old books and it doesn’t stop them from reading new ones. Can you imagine saying this exact same thing about music? People’s tastes change over time and they like new things- old things don’t stop us from consuming the new things. All the copyright lobbyists are doing is preventing the public from enjoying old games that can no longer be played because the hardware is dated or there are no viable copies left.
